"Rising Pollen Allergies: Impact of Climate Change and Survival Tips"

A 2.1 magnitude earthquake rattled the Richmond region on Monday night, centered between Glen Allen and Ashland, following a recent 4.8-magnitude earthquake near Lebanon, New Jersey. Earthquakes large enough to be felt by many people are relatively rare on the East Coast, with only about 20 quakes above 4.5 magnitude since 1950, compared to over 1,000 on the West Coast. The 2011 5.8 magnitude earthquake near Mineral was one of the most widely felt quakes in North American history.

New study confirms Turkey's 2023 earthquake as country's largest on record.

The twin earthquakes that hit Turkey and Syria in February were likely the most powerful doublet ever to occur on land, according to new research. The first earthquake had a moment magnitude of 7.95, and the second had an Mw of around 7.86. The earthquakes were caused by the interaction between different tectonic plates, and ruptured multiple fault segments, causing significant damage. The research highlights the need for countries prone to earthquakes to invest in strengthening structures and prepare the population to mitigate earthquake risks.
